why do scars hurt
i found a couple different possible answers from this website: http://ask.metafilter.com/53267/4-month-old-scar-still-hurts
The first reason could be an infection got trapped under the skin as it healed and it is still stuck in the area of the scar. Another reason could be (depending on how deep the wound was) that the outer layers healed normally and look fine but underneath the deeper layers are still trying to sort themselves out and heal, which would mess with your nerves causing the pain.
